To (all w/wm, it 11m/,7j concern:

Be it known that l, HENRY SNCLAIR DELA- MERE, a citizen of the United States, and a resident of Cloverdale, in the county of Sonoma and State of California, have invented a new and Improved Railway-Tie, of which the following is a full, clear, and exact description.

My invention relates to ties for use in track construction. Its principal objects are to furnish a light and strong' device of this character in which expansion and contraction of the track system will be provided for and in which the integrity of the securing devices is maintained.

Reference is to be had to the accompanying drawings, forming a part of this specication, in which similar characters of reference indicate corresponding parts in all the views.

Figure l is a perspective View of one embodiment of my improved tie. Fig. 2 is a broken enlarged longitudinal sectional detail on the line 2 2 of Fig. 1. Fig. 3 is a transverse view on the line 3 3 of Fig. 2. Fig. 4 shows one of the securing-bolts in side elevation, and Fig. 5 is a top plan view of one of the nuts.

My improved tie may be either east or rolled from steel or other metal, it being formed integrally or made up, as is desired, and comprises a base 10, the length and width of which may be the same as the ordinary wooden tie. From this base separated at a distance from one another equal to the space between the track-rails are supportsA A, each having side walls 11 11, which converge upwardly from the base and are connected by top walls 12, extending parallel to the base. Lying centrally of the base and connecting it and the side walls of the supports is a web 13, which may be equal in height to said supports and which may be omitted within them or between their side walls. This web is preferably strengthened by a flanged top 14, which is shown as merging' into the base at the ends of the tie, and throughout its length are openings 15, which render it lighter without undue sacrifice of strength. Along the edges of the base are upturned flanges 16 16. These, as illustrated, are omittedv between the side walls of the supports, their place being taken by central ribs 17. Transverse ribs 18 may also extend between the fianges centrally of the tie and adjacent to the inner side walls. All these ribs and flanges serve to strengthen the structure, while permitting it to be formed of comparatively thin material.

In the top of each support is a central opening 19 to permit the drainage of any moisture which may accumulate, and upon each side of this opening', they being situated diagonally of the support, are bolt-openings 20 20,which are preferably elongated longitudinally ofthe tie and which have inclined walls diverging downwardly. Each supportis recessed, these depressions being `furnished by peripheral iianges 20, and in these recesses are seated blocks 21 of some such yieldable material as wood or rubber. Each block has in its upper face a transverse slot and upon each side of this slot and closely adjacent to it openings in alinement with the support-openings 20. Through the support and block openings extend bolts 22, having wedge-shaped heads 23, which cooperate with the inclined walls and are of such size that they are held against upward movement through the support-openings While being capable of some play longitudinally of the tie. Their stems project above the blocks upon each side of rails 24,' which rest in the block recesses. These projecting ends are threaded to receive nuts 25, which are elongated in one direction by opposite projections 26 Q6, which when turned in the general direction of extension of the.tie may engage the rails to secure them in place upon the blocks.

This tie when set with its base upon the road-bed oers an ample surface for contact with the ballast to hold it firmly in place. The rails being bolted upon the yieldable blocks, the vibration resulting from the passage of trains is absorbed thereby, this being aided by the peculiar open arrangement of the supports. While the bolt-heads secure such engagement of the support-openings that they cannot possibly be drawn through, some lateral movement of the track is permitted to allow for expansion and contraction. The shape of the bolt-head also gives a much stronger arrangement than in the iiat head projecting at right angles from the stem, it being less liable to snap off. Furthermore, it will be evident that by the use of a minimum amount of material a maximum strength is secured, insuring economy in manufacture and in transportation.

It will be evident from an inspection of the drawings that the slots in the rail-supports IOO IOS

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A tie comprising a base, and separated rail-supports having' opposite side walls extending across the base and connecting top walls.

2. A tie comprising a base, and separated rail-supports having' opposite side walls extending' across the base and which converge upwardly and connecting top walls.

3. A tie comprising a base, separated railsupports having opposite side walls extending' across the base and connecting top walls, and an intermediate web connecting the base and side walls.

4. A tie comprising a base provided at its edge with longitudinal upturned flanges, and separated rail-supports having' opposite side walls extending' across the base and connecting top walls.

5. A tie comprising' a base provided at its edges with longitudinal upturned ilanges and with ribs extending between the flanges, and separated rail-supports having opposite side walls extending across the base and connecting top walls.

6. A tie comprising a base, separated railsupports having opposite side walls extending 1. The combination with a tie comprising a base and separated rail-supports having opposite side walls extending across the base and connecting' top walls, oi yieldable blocks resting' upon the top walls, and rails carried by the blocks and being secured to the supports.

8. The combination with a tie comprisingl a base and separated supports having openings, ot' yieldable blocks resting upon the supports, and bolts for securing' the rails upon the blocks and being movable laterally in the support-openings.

9. The combination with a tie comprising a base and separated supports having openings provided with downwardlydiverging walls` of rails carried 'by the supports, bolts having wedge-shaped heads situated in the support-openings, and nuts cooperating with the bolts and rails.

l0. The combination with a tie comprising a base and separated supports having openings, rails carried by the supports, bolts extending through the support-openings, and nuts threaded upon the bolts and having lateral projections contacting with the rails.

In testimony whereof l have signed my name to this specification in the presence or' two subscribing witnesses.
